In the punnet square, a represents the allele for red hair. This allele is recessive. Use the punnet square to determine what percentage of offspring will have red hair.

[question number = 02.2] Choose the correct set of sex chromosomes to fill in this genetic diagram (genetic cross).

Cystic fibrosis is an inherited disease caused by a recessive allele. Use the genetic diagram (genetic cross) to determine the probability that an individual has the cystic fibrosis where F = normal allele and f = cystic fibrosis allele.

The family pedigree diagram below shows a family with some individuals who suffer from cystic fibrosis – a disease caused by a recessive allele. It also shows some individuals who are carriers but do not have the disease and individuals who are neither carriers nor have the disease.

If James meets a woman named Ashley who is a carrier and they have a son, what is the probability that their son would have cystic fibrosis?

The family pedigree diagram below shows a family with some individuals that suffer from cystic fibrosis – a disease caused by a recessive allele. It also shows some individuals who are carriers but do not have the disease, and individuals who are neither carriers nor have the disease.

Calculate the probability of Ellie and David’s daughter having cystic fibrosis.
